Abstract

Tianjin Cihai Bridge is a hybrid structure of new cable-stayed bridge with giant wheel．Three wind tunnel models of hybrid structure were established in order to comprehensively understand and judge the structure's dynamic characteristics of wind action,and to study the vibration phenomenon by air wake．With tunnel test,wind force coefficients from different wind angel between the directions of bridge axis were acquired,and through the experimental observation and data analysis the phenomenon of vibration by air wake was judged.The result shows that the phenomenon of vibration by air wake will not occur after completion of the overall structure,but in the construction of the main tower only,if the design wind speed is close to the resonant wind speed the phenomenon of vibration by air wake will occur．The measure of setting partitions between the inverted Y towers can be used to improve the stiffness of the main tower,and then to avoid the occurrence of unstable vibration by air wake．
- wind tunnel test,
- hybrid structure,
- local wind force coefficient,
